Example Embodiment

[0018] The present invention will be described in detail below in conjunction with the drawings and embodiments.

[0019] Such as figure 1 , figure 2 , Figure 4 As shown, the present invention provides an underwater production facility disposal device, which includes a main truss 1, a pressure-bearing buoy 2 and a hoisting system; the main truss 1 is a quadrilateral structure, on which at least two pressure-bearing buoys 2 are arranged, and two The pressure buoys 2 are symmetrically distributed on the main truss 1, and the water volume in the pressure buoy 2 is adjustable; the hoisting system includes an upper hoisting mechanism 31 and a lower hoisting mechanism 32. The upper hoisting mechanism 31 is arranged on the upper part of the main truss 1. The disposal device is connected with the construction ship 6, and the lower hoisting mechanism 32 is arranged at the lower part of the main truss 1 for connecting the underwater production facility 7.

[0020] Further, the pressure-be...

Abstract

The invention discloses an underwater production facility disposal device. The underwater production facility disposal device is characterized by comprising a body truss of a quadrilateral structure,at least two pressure-bearing floating barrels fixedly arranged on the body truss and symmetrically distributed on the body truss, an upper hoisting mechanism fixedly arranged on the upper portion ofthe body truss and used for connecting a workboat, and a lower hoisting mechanism fixedly arranged on the lower portion of the body truss and used for connecting an underwater production facility. Theunderwater production facility disposal device can facilitate the hoisting of underwater production facilities of different specifications and types, the water quantity in the pressure-bearing floating barrels can be adjusted to facilitate the adjustment of the dead weight of the whole device while being lowered to facilitate the lowering and to increase the buoyancy of the whole device to compensate the lifting capacity of the workboat, the requirement of crane capacity is reduced, the expense of renting or purchasing hydraulic purging equipment is eliminated, construction costs are saved, and effective disposal treatment of the underwater production facilities is realized.

Description

technical field [0001] The invention relates to a disposal device, in particular to a disposal device applied to underwater production facilities such as underwater manifolds and underwater pipeline terminals based on anti-settling plates. Background technique [0002] The underwater production system can avoid the construction of expensive offshore oil production platforms, save a lot of construction investment, is less affected by disasters, and has strong reliability. With the continuous development of technology, it has become a mainstream development form of offshore oil and gas field development. [0003] After all production activities in an offshore oil and gas field are terminated, the offshore production facilities of the oil and gas field should be disposed of; the disposal of offshore engineering facilities can be divided into three methods: in-situ disposal, off-site disposal and conversion to other uses. [0004] The underwater production system consists of a v...
